| 摘 要： | 在桁架自升式平台模型试验中，由于在制作模型时不能将桁架腿直接按比例缩小，故需要将其等效为圆柱腿．根据水中受力相似的基本思路，利用ANSYS软件，提出确定等效圆柱腿外径的方法，并分析了试验中波高、波周期对等效外径的影响．

| Abstract: | In model experiment for the Jack-up platform, it＇s hard to scale the original truss leg directly. So it＇s needed to change the truss leg into an equivalent columnar leg. According to the similar criterion of force in the water and based on the ANSYS software, a way to determine the diameter of the equivalent columnar leg is proposed in this paper. At the same time, the effect of the wave height and wave period to the equivalent diameter is analyzed. |
